A CORPORATION I OF CURTAIN-FIXTURE.

useful Improvements in Curtain-Fixtures, of

which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.

This invention relates to curtain-fixtures, and relates especially to curtain-fixtures such as are employed in railway-cars and serve to securely hold a spring-actuated curtain in C any desired position.

.In the accompanying drawings; showing illustrative embodiments of this invention, Figure 1 is a front view, partly in section, showing one embodiment of this invention applied to a curtain. Fig. 2 is a detail sectional view, on a larger scale, showing the shoe. Fig. 3 is a transverse sectional view of the same on the line 3 3 of Fig. 2. Fig. 4 is an enlarged view of another form of shoe, and Fi 5 is a similar view of still another form 0 shoe.

In the illustrative embodiment of this invention shown in the drawings the curtain 17 is preferably provided at its lower end cured with a suitable counterweight 20 and secured at its u per end to a constantly-acting sprin -ro ler' 18. The curtain-stick 10, which may eof tubular form, is indicated as sein a suitable pocket at the lower end of the curtain in the usual way. This curtain-stick serves tosecure the shoes to the curtain and to allow a relative reciprocation between them, so that they properly cooper ate with the guideways 19 on either side of the curtain, which may be grooves of the usual form. The shoes when desired by operating the pinch-handles 16, which are connected with the shoes by suitable rods 12, although these pinch-handles and rods may be omitted, .if. desired.

As indicated in .Figs. 1, 2, and 3, each shoe 1 may be formed with a shoe-spindle 9,

mounted within a suitable opening in the curtain-stick and guided therein by a pin 14 members may take in the spindle ,which cooperates with a slot .15 in the curtain-stick. In this shoe rotating guiding members may be mounted for engagement with the uideway, and these tl ae form of guide-rolls Specification of Letters Patent.

3, with treads of gripping material-such, for instance, as corrugated metal, as indicatedmounted in the shoe by the concentricallylocated pivots 4. Each guide-roll may be provided with a non-circular 'eccentricallylocated retainer, and this retainer 5, as indicated in Figs. 2 and 3, may be polygonal and connect the two similar sections of the guideroll. The degree of eccentricityv of these retainers and their exact shape, including the number of sides, maybe varied so as to secure with the spring-pressure employed the desired holding power of the fixtureholding member in the form of the crosshead'6 is indicated as cooperating with these retainers, which fit loosely within the slots 7 in the cross-head. This c'ross-headis prefer: ably rigidly secured to the stem 8 by the pin 47 which of course may form a ri id riveted connection, although it may be Ioosely secured upon the stem for instance, and thereby connected with the plunger 11 within the curtain-stick. This plunger may be, as indicated, secured to the rod 12 of the corresponding pinch-handle, and this plunger is also engaged by the spring 13, which forces it outward. In this way a considerable pressure is always exerted between the holding member and the retainers, which forces the shoe outward and which also forces the guide-rolls outward into firm engagement with the guideway; When, however, the fixture is moved along the guideway, the guide-rolls are rotated by their frictional engagement with the guideway, and the engagement between the re tainer and holding member is of such a yielding character as to readily allow the movement of the parts during the adjustment of the curtain-fixture, but yet to efiectually The holding {power of this form of shoe is of course greatest when in cated in Fig. 2, since under these conditions the holding member engages the retainer at a fiat point thereof andat the lowest point.

The antifriction-rolls 2 may be pivotally mounted at the ends of the shoe and sometreads of the guiding members, as indicated, so as to be slightly out of contact with the guideways when the fixture is in normal horizontal position, these antifriction-rolls being by the pivot or pin 47,-

retain the curtain inadjusted position.

the position indiwhat behind the plane of the operative 'mal engagement with sai adapted to engage the the fixture to assist in horizontal position.

If desired, only a single holding guiding member may be employed in each shoe, as is indicated in Fig. 4, where the guideroll 24 is mounted to rotate about its concentricallylocated pivot 25 in the shoe 21, this shoe being mounted upon the shoe-spindle 30, operating Within the curtain-stick 31 and guided therein by the pin 32 and slot 33, as described. The antifriction-rolls 23 are also indicated as pivoted in either end of the shoe and normally out of contact with the guide- Way. The guide-roll 24, which of course has a tread of sufficiently gripping character to properly engage the guideway, is shown as formed with an eccentrically-located circular retainer 26, the degree of eccentricity being adjusted with relation to the spring-pressure, so 'as to give the proper holding power. This retainer is engaged by the folding member 28 in the form of a cross-head, the slot 27 being provided for inclosing and cooperating with the retainer 26. This cross-head is mounted on the stem 29. This plunger 34 may be connected, if desired, with the rod 35, and a suitable pinch-handle to retract the same and the plunger is also pressed outward by the spring 36 in the curtain-stick. If de sired, the antifriction-rolls may be omitted from shoes of this character, and one form of construction of this kind is shown in Fig. 5, in which the shoe 38 carries rotating guiding members in the form of the circular guiderolls 39, mounted to rotate about their concentric pivots 40. These rolls are provided with the eccentrically-located retainers 41, which are engaged by the holding member in the form of the cross-head 43, having slots 42 for the accommodation of these retainers. This cross-head is indicated as integral with the plunger 44, which passes loosely through the shoe 38 and is adapted to be mounted in the curtain-stick, as described, and connected with a pinch-handle, if desired.
